Theory of Magnetic Anisotropy in III_{1-x}Mn_{x}V Ferromagnets
M. Abolfath, T. Jungwirth, J. Brum +1
We present a theory of magnetic anisotropy in diluted magnetic semiconductors with carrier-induced ferromagnetism. The theory is based on four…
Magnetoresistance and electronic structure of asymmetric GaAs/AlGaAs double quantum wells in the in-plane/tilted magnetic field
O. N. Makarovskii, L. Smrcka, P. Vasek +3
Bilayer two-dimensional electron systems formed by a thin barrier in the GaAs buffer of a standard heterostructure were investigated by magnetotransport measurements. In magnetic f…
Pseudospin Anisotropy Classification of Quantum Hall Ferromagnets
T. Jungwirth, A. H. MacDonald
Broken symmetry ground states with uniform electron density are common in quantum Hall systems when two Landau levels simultaneously approach the chemical potential at integer fill…
Theory of Ferromagnetism in Diluted Magnetic Semiconductor Quantum Wells
Byounghak Lee, T. Jungwirth, A. H. MacDonald
We present a mean field theory of ferromagnetism in diluted magnetic semiconductor quantum wells. When subband mixing due to exchange interactions between quantum well free carrier…
